To add a method to a button, first create an action method:
Objective-C
-(void)someButtonAction:(id)sender {
// sender is the object that was tapped, in this case its the button.
NSLog(@"Button is tapped");
}Swift
func someButtonAction() {
print("Button is tapped")
}Now to add this action method to your button, you have to write following line of code:
Objective C
[yourButtonInstance addTarget:self action:@selector(someButtonAction) forControlEvents:UIControlEventTouchUpInside];Swift
yourButtonInstance.addTarget(self, action: #selector(someButtonAction), forControlEvents: .TouchUpInside)For ControlEvents parameter, all members of ENUM UIControlEvents are valid.
